A nurse is assessing a client's cranial nerves as part of a neurological examination. Which of the following actions should the nurse take to assess cranial nerve III?

Choice A Reason: This choice is incorrect because urinary hesitancy is not the priority finding for the nurse to address.

Urinary hesitancy is a difficulty or delay in starting or maintaining a urine stream. It may be caused by various factors such as prostate enlargement, urinary tract infection, medication side effects, or psychological issues. It may cause discomfort, pain, or urinary retention, but it does not pose an immediate threat to the client's life.

ChoiceB Reason: This choice is correct because dysphagia is the priority finding for the nurse to address. Dysphagia is a difficulty or inability to swallow food or liquids. It may be caused by various factors such as stroke, Parkinson's disease, dementia, esophageal cancer, or oral infections. It may cause malnutrition, dehydration, aspiration, or choking, which can lead to serious complications such as pneumonia, sepsis, or death. Therefore, the nurse should assess the client's swallowing function and provide appropriate interventions such as modifying the diet texture, using thickening agents, or teaching swallowing techniques.

ChoiceC Reason: This choice is incorrect because swollen gums are not the priority finding for the nurse to address. Swollen gums are an inflammation or enlargement of the gingival tissue that surrounds the teeth. They may be caused by various factors such as poor oral hygiene, gum disease, vitamin deficiency, medication side effects, or hormonal changes. They may cause bleeding, pain, or infection, but they do not pose an immediate threat to the client's life.

Choice D Reason: This choice is incorrect because pruritus is not the priority finding for the nurse to address. Pruritus is a sensation of itching that affects the skin. It may be caused by various factors such as dry skin, allergies, eczema, psoriasis, liver disease, or kidney disease. It may cause discomfort, scratching, or skin damage, but it does not pose an immediate threat to the client's life.

Choice A: Eliciting the gag reflex is a way to assess cranial nerve IX (glossopharyngeal) and X (vagus), which are responsible for the sensation and motor function of the pharynx and larynx.

Choice B: Testing visual acuity is a way to assess cranial nerve II (optic), which is responsible for the sense of vision.

Choice C: Observing for facial symmetry is a way to assess cranial nerve VII (facial), which is responsible for the motor function of the facial muscles and the sensation of taste.

Choice D: Checking the pupillary response to light is a way to assess cranial nerve III (oculomotor), which is responsible for the motor function of most of the eye muscles, including those that control pupil size and lens shape.
